xfrm: fix dflt policy check when there is no policy configured
commit ec3bb890817e4398f2d46e12e2e205495b116be9 upstream.
When there is no policy configured on the system, the default policy is
checked in xfrm_route_forward. However, it was done with the wrong
direction (XFRM_POLICY_FWD instead of XFRM_POLICY_OUT).
The default policy for XFRM_POLICY_FWD was checked just before, with a call
to xfrm[46]_policy_check().
CC: stable@vger.kernel.org
Fixes: 2d151d39073a ("xfrm: Add possibility to set the default to block if we have no policy")
